Tulisa has spoken out after Mazher Mahmood was sent to prison, saying it's a new beginning for her.

Disgraced reporter and self proclaimed 'Fake Sheikh' was jailed on Friday for 15 months for tampering with evidence.

Following a two-week trial at the Old Bailey, a jury found the former News of the World journalist and his driver Alan Smith, 67, guilty of plotting to pervert the course of justice.

Reacting to the verdict, Tulisa said a chapter has finally been closed.

Speaking in her documentary, the singer shares: "I would say that's the end of that story but the beginning for me beause that's the point that it's really closed that chapter.

"I don't think I could ever fully, fully let it go even if I kept it at the back of my mind and my subconcious. Part of me would have really felt that injustice, but now there's nothing for me to hold onto. It's done a full circle. What goes around comes around. It couldn't ever be more relevant - karma."

She said the entire thing has been totally bizarre.

"If you were to go back in time and someone was to say to me three years ago, 'OK, Mazher Mahmood he is going to be facing the same amount of time in jail as you were, he is going to be the one in the firing line and the press are going to put him on front pages and destroy his reputation as they did to you... it's bizarre. It really is."

Tulisa continued: "He doesn't see any wrong in what he's doing. I don't think without these serious consequences that he's now on the receiving end of he would have ever stopped."

The Old Bailey trial had heard that Mahmood and Smith conspired to suppress evidence in the N-Dubz star's trial, which was thrown out at Southwark Crown Court in July 2014.

The singer says it's a new beginning for her

The singer had been accused of arranging for Mahmood to be sold £800 of cocaine by one of her contacts following an elaborate sting for The Sun on Sunday in May 2013.

During a meeting at the Metropolitan Hotel in London, Mahmood posed as a film producer and plied Miss Contostavlos with alcohol as they discussed an acting role alongside Hollywood star Leonardo DiCaprio.

As Smith drove the former X Factor judge home to Hertfordshire, she allegedly spoke about a family member who had a drugs problem.

When he was interviewed by police about the journey more than a year later, Smith, of Dereham, Norfolk, recalled the conversation.

Mahmood got 15 months in jail

But a day later, after speaking to Mahmood and emailing his draft statement, the singer's anti-drugs comments were removed, the court heard.

At a pre-trial hearing, Mahmood, of Purley, south London, denied being an "agent provocateur" or that he discussed the drugs conversation with Smith.

But when he was questioned at length in the trial, Mahmood appeared to concede he had talked to Smith about what Miss Contostavlos said about drugs in the car. The case was subsequently thrown out.
